6.6 General Purpose I/O (GPIO)

6.6.1 Overview

The NuMicro

®

NUC029LEE/NUC029SEE has up to 45 General Purpose I/O pins to be shared

with other function pins depending on the chip configuration. These 45 pins are arranged in 5
ports named as GPIOA, GPIOB, GPIOC, GPIOE and GPIOF. The GPIOA/B/C/E port has the
maximum of 15 pins and GPIOF port has the maximum of 2 pins. Each of the 45 pins is
independent and has the corresponding register bits to control the pin mode function and data.

The I/O type of each of I/O pins can be configured by software individually as input, output, open-
drain or Quasi-bidirectional mode. After reset, the I/O mode of all pins are depending on
Config0[10] setting. In Quasi-bidirectional mode, I/O pin has a very weak individual pull-up
resistor which is about 110~300 K



for V

DD

is from 5.0 V to 2.5 V.

6.6.2 Features



Four I/O modes:

-

Quasi-bidirectional

-

Push-Pull output

-

Open-Drain output

-

Input only with high impendence



TTL/Schmitt trigger input selectable by GPx_TYPE[15:0] in GPx_MFP[31:16]



I/O pin configured as interrupt source with edge/level setting



Configurable default I/O mode of all pins after reset by Config0[10] setting

-

If Config[10] is 0, all GPIO pins in input tri-state mode after chip reset

-

If Config[10] is 1, all GPIO pins in Quasi-bidirectional mode after chip reset



I/O pin internal pull-up resistor enabled only in Quasi-bidirectional I/O mode



Enabling the pin interrupt function will also enable the pin wake-up function.
